' PORTABLE BATTERY-LIGHT.

Speciflcation of Letters Patent.

Patented Feb. 9, 1915.

Application filed May 26, 1913. Serial No. 789,821.

'10 part of the same, to be a full, clear, and

exact description thereof.

The invention relates to a novel form t or portable electric battery light and hasfor its object to produce a light of this character which is extremely cheap to manu-.

facture and efficient in operation.

To theseends the invention consists in thenovel construction, arrangement and combination of parts hereinafter described and more particularly set forth in the claims. i

' In describing the invention in detail reference will be made to the accompanying drawingsin which- Figure 1 is a front elevation of my novel battery light. Fig. 2 is a side view of the same. Fig. 3 is a vertical sectional view on an enlarged scale on line 'wm, Fig. 2.. Fig. 4 is a vertical sectional view on an enlarged scale on line y-' Fig. 1'.' Figs. v5 and 6 are details' Fig. 7 is a modified construction. 1

Referring to the drawings, 1 represents a dry battery which is proyided with the customary terminals or binding posts 2 and 3 and thumb nuts 2 and 3', respectively. Said battery is also provided with a handle 4 upon the top, an opening 5 in the bottom and elastic loops 6 upon the side, as shown .in Fig. 1 and more particularly described in a copending application filed of even date herewith.

' Removably-mounted upon the top of the battery 1 is an electric light receptacle which comprises a body portion 7 of any desired shape or material, such as hard rubber,

I fiber, or composition. Said body portion 7 is preferably molded into the-shape shown in the drawings and comprises a fiatbase 8, a rounded top 9, and a funnel-shaped opening 10 in the' front side thereof. At the apex of the funn'eLshaped opening 10 is a screw-threaded o'peningll which is adapted to receive the base of an electric lamp 12,

- and extending from the top of the body portion 7 to said screw-threaded opening 11 of the body portion 7, and is provided with receptacle are a series of spring-clips 26 seis a hole or opening 13.

Molded in the body portion 7 are two flat metal contact strips 14 and 15, respectively. The contact strip 14 has its inner end 16 located above the screw-threaded opening 11 and is provided with a screw-threaded hole 17 in alinementwith the hole 13, as shown in Figs. 3 and 4. Extending into the hole 13 and mounted in the screwthreaded hole 17 is a thumb contact-screw 18. The outer end 19 of said contact strip 14 extends through the base 8' and is bent outwardly so as to project beyond the side 7i0 a transverse slot 20. v v I The contact strip 15 has its inner end 21 provided with a raised contact point 22 arranged at the inner end of the screwthreaded opening 11, as shown in Fig.- 4,

- and has its outer end 23 extend through the base 8 and bent outwardly in the line with, but in the opposite direction from, the outer end 19 of contact strip 14, and projects beyond the side. of the body portion 7, and is provided with a longitudinal slot 24. Removably mounted in the elastic loops 6 is a candle extension 25, and mounted upon. the exterior of the body portion 7 of the lamp cured at one end ing a shade.

With the above construction it will be seen that the electric light receptacle can be quickly mounted upon the battery 1 by loosening the thumb-nuts 2 and 3 and en gaging the terminals 2 and'3 with the slots 20 and 24, respectively, in the contact-strips 14 and 15. When the terminals are thus engaged and the thumb-nuts 2' and 3' tightened, the light receptacle will be securely held in position upon the. top of the battery. It now the lamp 12 is inserted in the screw-threaded opening 11, the customary contact point upon the end of the base will engage the contact point 22 on the contact-strip 15, as shown in Fig. 4. If new the thumb contact screw 18 is rotated so as to engage the customary meta'l shell upon the base of the lamp 12, as also shown in said Fig. 4, a circuit will be completed from the battery 1 through the lamp '12 and cause the same to by screws 27 for support:

be lighted. 'B'y rotating thedzhumb contact screw in the opposite direction the lamp will be extinguished.

. of an electric light receptacle comprising a- Fig. 7 shows a modified arrangement in which the lamp receptacle 7 is mounted upon the front of the battery 1, instead of upon the top. Thisis accomplished by having the contact strips 14' and 15 extend out through the back or top of the body portion 7 and the outer ends bent over at right angles upon the top of the battery as shown.

It will be seen that iny novel form of battery is extremely simple and cheap tomanufacture; that it is of a convenient shape to be carried a coat-pocket or the pocket of an automoblle; andthat when the battery is exhausted the lamp receptacle can be quickly detached and attached to a. new battery. It will also be seen that by means of the shade-holder clips a suitable covering canbe placed over the lamp soils to adapt it for use in a dark room where photographs are developed.

What I claim as my invention and desire to secure by Letters Patent is:

1. The combination, with an electric battery provided with a pair of binding posts,

' body portion, an electric lamp. removably mounted therein, a contact strip having one L end arranged to contact with said electric binding posts, and a second contact strip lamp and the other end arranged to be re movably attached to one of the battery having one end provided with means adapted to engage and disengage said electric lamp and the other end arranged to be removably attached tothe' other of saidbattery binding posts.v A

, 4. The combination, with an electric battery provided with a pair of binding-posts, of an electric light rece tacle comprising a body portion having a .unnel-shaped opening in the front thereof, an electric lamp removably mounted in the apex of said 4 opening, a contact strip having its inner end located within said body portion at the inner end of the funnel-shaped opening and its outer end located outside of said body portion and provided with a longitu-, dinal slot adapted to receive one of said battery binding-posts, and a second contact strip having its inner end located within said body portion above the inner end of the funnel-shaped opening, a thumb contact 7 screw mounted in said inner end and adapted to engage and disengage the base ofthe electric lamp, and a transverse slot in the "outer end of said-contact strip adapted to receive the other of said binding posts;

5. The combination, with an electric battery provided with a pair of binding posts,

of an electric light receptacle removably secured to said binding posts andhaving a funnel-shaped opening, an electric lamp removably mounted in said opening, and a thumb contact. screw upon the exteriorof said light receptacle for lighting and extinguishing said lamp.

6. The combination, with an electric battery provided with a pair of binding posts, of an electric light receptacle removably secured to said. binding posts and having a funnel-shaped opening, an electric lamp removably mounted 1n said open1ng,a series of spring clips upon the exterior of said opening, and means upon the exterlor of said receptacle for operating said electric lamp.

7., The combination with an electric battery provided with a pair of binding-posts, of an electric light receptacle removably secured upon said binding-posts. an electric lamp'removably mounted in said receptacle 7 and means for lighting and extinguishing said lamp. j I I LEROY A. WILLIAMSON.
